The 42-year-old talk show host announced on twitter she was set to wed Christian Evans, in what will be her second wedding following her divorce from artist Rob Sussman after 10 years of marriage in 2003.
She wrote: "Thrilled to share some happy news with you..... I'm engaged! :) The cat is out of the bag. Phew! I'm terrible at keeping secrets
Ricki - who has sons, Milo, 14, and Owen, 10, from her previous marriage - recently joked Christian was "a nobody" but continued to be special to her.
She said: "He's a nobody, but he's somebody to me. He's everything to me. I'm totally in love. I'm happier than I've ever been."
Just last year Ricki - who is also known for appearing as Tracy Turnblad in the 1988 version of musical 'Hairspray' - was forced to flee her rented home in Los Angeles after it caught on fire.
However she and her two sons managed to escape the blaze unharmed, although everything inside was lost.
